In 'order 5 are provided at spaced intervals throughoutv to strengthenthese grooves, they are lined r the height of the wall, the sockets and closed with dove-tail sockets or channel members 3, ends being preferably produced froma sinpreferably formed ofv metal, which are progle blank of `material such as. sheet metal, vided with sides 3a bent from the central castor otherwise. bottom portions thereof in the same direction toward each other to provide converging side portions having curved edges or vflanges 3b forming shoulders adapted to conform to the corners or edges of the grooves 2 in the wall 1, as fairly shown in Figs. 1, 2

and 6 of the drawings. The sockets or chany nel members 3 are preferably formed of blanks or sect-ions of sheet metal, preferably galvanized, and with ends 4 produced by severing the corners of the blanks and turned at right angles between the sides of the socket to prevent the latter collapsing inwardly' towardeach other, thereby strengthening and reinforcing the'socke'ts or channel members, which are set into the concrete wall and extend flush with the same, either by molding the wall material around the sockets or otherwise. The ends 4 are shaped to conform to the dovef'tail crossed section of the sockets or channel members as shown.

j A plate or member 5 is provided with the rearwardly extending spaced or -top and bottom flanges 5. and reduced centrallugs 6,

said flanges stii'ening the plate and straddling or spanning the sockets and the lugs beingi adapted to enter the forward ends of the ove-tailed grooves 2 or the sockets or .channel members -3 set therein, in the concrete wall 1. A slot 7`is formed transversely through the plate 5 and having closed ends as shown in the preferred construction is adapted to receive thetie. or key strip 8,

which has formed integrally thereon, a rearwardlyextending dove-tailed lportion 9, whlch is adapted to extend into the groove 2 or the socket 3 between thesides of the latter, and to fit snugly therein. Obviously the portion'9 is inserted and turned when engaged in the groove or socket. The strip 8V is provided with one or more, preferably two openings 10, one of .which is adapted to receive one end 11a of a substantially4 U-shaped tie-iron 11, which latter is disposed in an inverted position when engaged in an opening 10 to contact with the plate 5- as-clearly shown in Figs. 2 and 3 ofthe drawings. fllhedopposite end l1b of the said tie-iron 11 1s a tile-blocks or masonry 13 and produced in the form of sockets in the tops of the latter *at the points where necessary, so that vthe lugs will be readily 4held in position adjacent the concrete wall, and may be anchored therein'by concrete 14 or otherwise. V Obviously,' a plurality of -such tie-members o'r irons may be employed. The device shown4 1s adapted for two.

From the foregoing description it will be apparent that the platemember 5 will be readily held against the concrete wall 1due to the rearwardly extending lugs 6, which enter the channel or groove 2 or the socket qheld therein. The portion 9 of the key strip 8 snugly fitted in the groove 2, is prevented lfrrm turning by reason ofthe lugs 6, slotx7 apted to seat in an opening v12, in the' flangesb forming shoulders as heretofore I specified.

In Fig. 7 of the drawings, 'openings 10 corresponding to the openings 10 are provided in the plate constituting thetie or key strip 8, and these may be arranged in staggered relation or in a line as desired to receive inverted U-shaped tie-irons or stripsv 11 to connect the blocks of the masonry or facing wall 13 at a .joint as shown in this figure, as described in connection with the tie-iron 11. When the openings 10 are arrangedas in Fig. 5, the tie-irons 11 will clear one another where engaged with the plate 8 or key strip formed thereby. Obvil ously, the tie-irons .may be made o`f the required length and are anchored and insemicircular cut-outs in the-top portions o-f'the adjacent building blocks,'monoliths or the `like in linetherewith, Qtherwise, the 'construction in thisI form of the invention is Vthe same as that described in connection with l Figs. 1 to 6 inclusive. f l

In Fig. 8 of the drawings a combined tie and keystrip or plate 15 is shown, which is ad'a ted'for use in connection. with brick Wal s or similar facings or veneering. The A brick wall is shown at 16 and the plate 15 has 'a dove-tailed end 17 to engage the dovetailed groove or socket 2 or 3 as previously described, and the enlarged end of this wedged-shaped plate. is provided with an opening as indicated atj18 and an upturned flangeA or lip 19 at one edge, preferably the outer edge, to be v locked in the mortar orv other binding between the brick or the like. The mortar will also pass into the slot or .opening 18 and when hard, will firmly anchor and connect or tie the against separation.

'In the construction shown in Figs. 9 and 10 of the drawing, a tie or key strip 2() is employed having a downturned 'outer-fend or flange 21 to be'anchored in the wall or block; as are the tie-irons 11 and 11 ad'is covered with mortar while Ithe dove-tail `end 22 is held in the dove-tailed groove 2 or. socket 3, as heretofore described. The plate or tie members may be ,Hat sheet metal or otherwise. Thus it will be understood and seen that the tile veneering will be p0sitive- 1y held in position adjacent the concrete wall of the building structure' and thatrthe tile blocks will notV have to be broken or special forms of blocks be required in order to use the'anchoringA means.

parts together A' struction shown in our prior patent, or the dropping of the tie 0r key members engaged therewith and with the veneering wall will be prevented. This also provides for -facility in' the construction and the tie members" cannot drop.

Many minor changes in detail ofA con-1 struction may be resorted to without departure from the spirit of the invention.

Of course, it is to be understood that the socket or channel members 3 are nailed or otherwise secured on a form for producing a concrete wall, so that when the concrete is poured and set or hardened, the' sockets 'o'r channels, reinforced as described with 4 metal, will be produced.
